18 Best Long-Sleeve Swimsuits That You’ll Reach for All Summer
When you think of a long-sleeve swimsuit, your mind probably goes to a utilitarian rash guard devised to keep you safe from water sport scrapes, and give you an extra layer of protection from the sun (especially if its made with a UPF fabric). And while those are definitely benefits, we’ve actually seen tons of innovation in this category. The best swimsuit brands are making cute surf-inspired one-piece swimsuits, trendy puff-sleeve silhouettes, and long-sleeve crop tops that pair perfectly with a high-waist bikini bottom, and two-piece versions that double as cover-ups–all of which you can rock even if you're more of a beach reader than kayaker.
Whether you prefer the athletic look or simply want a little more sun protection, these long-sleeve, editor-approved suits are beckoning us like the waves—and you can bet we’ll be adding one to our poolside repertoire.
Pro tip: If your long-sleeve bathing suit comes equipped with a built-in shelf bra or padding, you don’t have to wear anything underneath it. However, if you like extra support, layer it over a bikini top designed for a larger bust.

This might look like a bold printed top in the front, but a subtle detail is hiding in the back—a fun cutout. We love how it can be paired with a variety of matching bottoms like the briefs pictured, or high-waisted styles.
Pros: This top comes in several unique prints like this Italian lemon tree and polka dots.
Cons: It hits barely below the ribcage, so it’s very cropped.
